Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
can: etas_es58x: es58x_rx_err_msg(): fix memory leak in error path<br />
<br />
In es58x_rx_err_msg(), if can->do_set_mode() fails, the function<br />
directly returns without calling netif_rx(skb). This means that the<br />
skb previously allocated by alloc_can_err_skb() is not freed. In other<br />
terms, this is a memory leak.<br />
<br />
This patch simply removes the return statement in the error branch and<br />
let the function continue.<br />
<br />
Issue was found with GCC -fanalyzer, please follow the link below for<br />
